Aveo head swap oil leak

[Jnova]

would a 2007 head gasket seal on a 2004 block?

[Eg.h2o]

Maybe wiith a 2007 gasket. From my understanding, the back drain will just be blocked off if you use the correct gasket (the block is solid at that area on a 2004) If you use the 2004 gasket, the drain on the head won’t have any gasket fully surrounding it......thus the leak.

After looking further at a 2004 block, I don’t see enough there for the rear drain to seal against....so please disregard my prior info. I think you can’t use the dual drain head on a single drain block. Sorry.
